took my son out this weekend to big boulder in the poconos, They only had one park open. This was good for my son, but I am too old for park (too many injuries)
I was riding down the sides past the rails and the jumps. The sides were really Icy, and I had a lot of trouble controlling my self with my arbor formula. I could not hold an edge trying to heel side stop or even toe side stop. not sure of the technical terms but it felt sloppy and there was not much control
the hill was not a challenging hill, I believe it was rated easy (freedom park, big boulder)

I wound up switching to my older 2010 sims protocol, this seemed to be a little more stable to me.

Last year I started out snowboarding late in the season, so have only ridden 3 other times. At the end of last year i was linking turns (definitely not carving) and not falling from top to bottom of easier hills

At your weight, sims will work better because of longer effective edge, keep edges sharp and riding ice is about "relaxed confidence"

the above is why i switched back to the sims my thought process was that it was a longer/stiffer board and less rocker, I think I have to work harder on the relaxed part of it. It was a very busy day, only mountain open in my area, and I am always concerned that at my size, I will barrel some kid over and break something, so I tend to ride less agressively till i have better control.

You've ridden 3 times, you went riding on the worst day of the year for someone at your level, and you haven't figured out how to stick an edge in and manipulate your weight to drive the board in and stay slow.

You're on boiler plate east coast ice. Other than a hell of a lot of trail and error coupled with balance and knowing your equipment nothing is going to help you.

Get an edging tool and a gray gummy stone. Use the gummy stone to touch up edges after riding, it helps keep them sharp. Use the edging file when they get really bad. Keep those fuckers sharp. That will help some, but listen to these guys here, they know their shit. It's less to do with equipment and more to do with practice. I rode rock solid ice last year on my old Burton Bullet rocker and even without sharp edges on that fairly flexible board I was able to stay up fine.

Full rocker probably didn't help. Arbor's rocker is great, and has the griptech edges, but I'm guessing being on full rocker, on ice, after 3 days of boarding total makes for some hairy moments.

I've been on Socal ice (60F day followed by 25F days) on the NS my second year, thinking, "this thing has vario grip I'm fine" not knowing wtf I was doing still. And ended on my ass a couple times.

Then I realized the edge technology doesn't help you stop, it helps you control your riding. Once I figured that out and stopped thinking it would help me come to a complete stop on ice but would allow me to keep an edge and ride the ice out (and bleed speed especially by turning back uphill) I've been fine since.

As another ice coaster I would avoid making any kind of hard turns once you hit the patch of ice if you can. Ride it through and be prepared to hold an edge once the snow gets a little softer. Stay low with knees flexed and be prepared to drive your edges in if you need to stop or have somewhat a controlled slide to avoid others.
